Refrigerant: Description and Operation
REFRIGERANT SYSTEM DYE
Fluorescent refrigerant system dye is added to the refrigerant system at the factory to assist in refrigerant system leak diagnosis using a
Rotunda-approved ultraviolet blacklight. It is not necessary to add additional dye to the refrigerant system before diagnosing leaks, even if a significant
amount of refrigerant has been removed from the system. Additional refrigerant system dye should only be added if more than 50% of the refrigerant
system lubricant capacity has been lost due to a fitting separation, hose rupture or other damage. Refer to Heating and Air Conditioning.
